Harbor Dredging

May 3, 2007

You may have noticed increased harbor dredging activity this season.  The first dredging, which is completed, was the hydraulic portion.  Through this method about 3,000 cubic yards of sand was removed from the harbor entrance.  This dredging is an annual event.  Prior to sand removal, permits from the DEQ, Army Corps and Antrim County Soil Erosion had to be obtained.  In addition the sand was tested.  The sand was pumped into a temporary holding area where the water was allowed to drain.  After draining the sand it was trucked off to an approved location.

The second type of dredging is mechanical dredging.  Mechanical dredging in our harbor is rare and the only reason we are doing it at this time is due to low water levels and “humps” in the harbor.  We strive to have at least a depth of 7 feet throughout the harbor.  This depth is needed for the deeper draft boats.  In the past we have had to turn boaters away because of their draw.  Again permits have been obtained from the DEQ, Army Corps and Antrim County Soil Erosion Control.  We anticipate at this time that 1,700 cubic yards of clay will be removed from the harbor in selected locations.  The clay material will be placed in a holding area and then trucked away to an approved site.  This dredging is to be completed by May 15th.

We are aware that these activities are inconvenient to some folks.  We hope you will be patient and understand these activities need to be done in order to provide the best harbor in Michigan.
